Specification of Letters Patent.

Patented April 23, 1907.

Application filed December 20, 1906. Serial No. 348,730.

To all whom it may concern.-

Be it known that I, CHARLnsW' ALTER, a cltlzen of the United States,residing 111 New York, in the borough of Richmond, county.

of Richmond, and State 01'' New York, have invented certain new anduseful lmprove ments in Siphon-Heads, of which the following is aspecification.

This invention relates to an improved siphon-head for dispensingcarbonated liquids from glass siphons.

The siphon-heads generally used are made of tin, the surface of whichsoon tarnishes and presents a dull and unattractive appcarance.

The object of this invention is to improve the appearance and diminishthe weight of the siphon-heads by employing aluminum for the body of thesame.

Another object of the invention is to improve the connection of theglass tube with the siphon-head in supporting the glass si hon-tube in areliable manner in the siphonead, so as to prevent the breakage of thetube; and the invention consists of a siphonhead, the body of which ismade of aluminum which is cast around an interior hard-metal sleevewhich supports the valve-actuating lever and the spring of the valve,and in which the spout and the interior connection are made of tin insuch a manner that the carbonated water comes only in contact with thetin on being discharged.

The invention consists further of the combination, with a siphon-bottle,of a siphontube having a rim at its upper end and supportedby a rubbersleeve extending around the siphon-tube, said sleeve being provided witha circumferential flange which is retained on the siphon-neck by theplacing of the siphon-head thereon.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection of my improved siphon-head, showing the valve in closedposition, Fig. 2 is a similar section with several of the parts removed,Fig. 3 is a perspective view of the elastic socket for supporting theglass tube in the bottle, and Fig. 4 is a section on line 4, 4, Fig. 1.

Similar letters of reference indicate correspending parts.

Referring to the drawings, (t represents a glass siphon-bottle, Z) theglass tube of the The head It consists of an internally threaded neck d,a tubular portion 61 above the same, a cap d applied to the upper end ofthe tubular portion, and a spout s that is connected with the tubularportion above the neck (Z. In the tubular portion or stem (1 is arrangeda cylindrical sleeve 0 of brass or other hard metal which is supportedon an elastic washer w through which the valve-stem f passes in upwarddirection. Said valve-stem is provided with a head 1 at the upper end,between which and the elastic packing is interposed a helical spring bywhich the valve at the lower end of the stem is pressed in upwarddirection against a seatf" arranged in the spout s. The valve-stem fpasses through an opening in the upper portion of the spout. Said stemis extended above the hcadf and is engaged at its upper end by thecurved inner end of a lever g, the inner portion 9 of which is supportedin an opening 0 in the hardmctal sleeve a, while its middle portionpasses through slots in the sleeve, and the tubular portion to theoutside ol" the latter.

A metallic exteriorly threaded collar d,

which is split at one point of the same,is in-.

scrted between the neck of the bottle a and the internally threaded neck(Z of the siphonhcad so as to make a firm connection between the neckol" the bottle and the siphon-head. The neck (Z and the tubular portion(Z are made of one integral tubular body of aluminum, which is spun atthe upper part around the hard-mctal sleeve and in suitable form aroundthe lower part, an opening being made at one point in the tubularportion, above the neck, for casting in the spout and the interiorconnection of the same with the glass siphon-tube, as shown in Figs. 1and 2. The casting of the spout and the interior connection is made in asuitable mold after the neck and tubular portion are made, so that theintimate connection of the tubular portion and. neck of the siphon-headis obtained. A hole for the valve-seat and a hole for the valve-stem inthe spout are either obtained by coring or drilling, as desired. By thisarrangement the carbonated liquid, on being discharged on the opening ofthe valve, only comes in contact with the interior surface of the tinconnection of the spout and does not come in contact with the aluminumbody of the siphon-head, while at the same time the appearance of thehead is greatly improved owing to the property of aluminum of remainingbright and untarnished. The cap and connecting-collar are likewise madeof aluminum, so that thereby not only the apreduced, and in place of themore expensive of the carbonated liquid pearance of the siphon-head isgreatly improved, but the weight of the same greatly tin, aluminum,which is cheaper than tin, is substituted for the body of thesiphon-head.

The operation of the valve, in opening and closing the same by the leveragainst the tension of the spring, is the same as in siphons heretoforein use, but the connection of the glass tube with the neck of the bottleis made by providing the up er end of the siphontube with an outward-bent short rim 1" and placing a rubber socket r around the same, saidsocket or sleeve being provided with a circumferential flange r madeintegral therewith which is held firmly in position between the rim ofthe bottle and the interior tin-filling of the siphon-head, as shown inFig. 1. The rubber socket or sleeve with its circumferential flangeholds the siphon-tube firmly in position and prevents it from beingbroken or injured while the bottle is in transit or when the same iscarelessly handled, while at the same time the circumferential flangeproduces the tight seating of the siphon-head on the bottle and preventsthe escape of any gas in the bottle.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A siphon-head comprising an exterior shell and cap, said shell beingformed of an internally threaded neck and a tubular upper portion, ahard-metal sleeve in said tubular portion, a tin valve-supporting bodywithin said shell at its lower portion, and a spout formed integral withsaid body and extending without said shell. 2. In a siphon-head, thecombination of an 1 exterior shell formed of an internally threaded oneck and a tubular portion above the same, a hard-metal sleeve in saidtubular portion, a tin body provided with a valve-seat and located atthe lower part of said tubular portion,

a valve to coaot with the valve-seat in said 5 body, a spring-actuatedstem for said valve extending upwardly into said sleeve, and avalve-operating lever supported within said sleeve.

3. In a siphon-head, the combination of a shell comprising an enlargedneck and a tubular portion extending upwardly therefrom,

a tin body located within said shell at the lower part of said tubularportion and provided with a valve-seat and a spout, a sleeve within saidtubular portion above said body, a valve to coact with said valve-seat,a stem for said valve extending upwardly into said sleeve, a headcarried by said stem, a spring interposed between said head and saidbody, (30

and a valve-operating lever extending into and supported within saidsleeve and abutting against the upper end of said stem.

4. In a siphon-head, the combination, with a siphon-bottle and asiphon-head, of a glass siphon-tube provided with a rim at its upperend, and an elastic sleeve located at the upper end of the siphon-tubeand provided with a circumferential flange or packing interposed betweenthe neck of the bottle and the neck of the siphonhead.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
